How do birds flock? Researchers do the math to reveal previously unknown aerodynamic phenomenon

In looking up at the sky during these early weeks of spring, you may very well see a flock of birds moving in unison as they migrate north. But how do these creatures fly in such a coordinated and seemingly effortless fashion?

Ultrasensitive photonic crystal detects single particles down to 50 nanometers

Using an ultrasensitive photonic crystal, TU/e researchers were able to detect single particles down to 50 nanometers in diameter. The new research has just been published in the journal Optica.

A NASA rover has reached a promising place to search for fossilized life on Mars

While we go about our daily lives on Earth, a nuclear-powered robot the size of a small car is trundling around Mars looking for fossils. Unlike its predecessor Curiosity, NASA's Perseverance rover is explicitly intended ...

A novel universal light-based technique to control valley polarization in bulk materials

Electrons inside solid materials can only take certain values of energy. The allowed energy ranges are called "bands," and the space between them, the forbidden energies, is known as "band gaps." Both of them together constitute ...

Lead-vacancy centers in diamond as building blocks for large-scale quantum networks

Much like how electric circuits use components to control electronic signals, quantum networks rely on special components and nodes to transfer quantum information between different points, forming the foundation for building ...

Nanofibers rid water of hazardous dyes: Researchers develop efficient filters based on cellulose waste

Using waste to purify water may sound counterintuitive. But at TU Wien, this is exactly what has now been achieved. Researchers have developed a special nanostructure to filter a widespread class of harmful dyes from water.

Making light 'feel' a magnetic field like an electron would

Unlike electrons, particles of light are uncharged, so they do not respond to magnetic fields. Despite this, researchers have now experimentally made light effectively "feel" a magnetic field within a complicated structure ...

Light stands still in a deformed crystal

AMOLF researchers, in collaboration with Delft University of Technology, have succeeded in bringing light waves to a halt by deforming the two-dimensional photonic crystal that contains them. The researchers show that even ...

Researchers find oldest undisputed evidence of Earth's magnetic field

A new study, led by the University of Oxford and MIT, has recovered a 3.7-billion-year-old record of Earth's magnetic field, and found that it appears remarkably similar to the field surrounding Earth today. The findings ...

Previous theory on how electrons move within protein nanocrystals might not apply in every case

Researchers believe that understanding how electrons move within small, natural systems could power a more sustainable future for our energy grid.
